DIY Catch Can write up

Aight here is my DIY catch can thread... I will list all the parts I used and where I got them... I know some shit is chinese crap, but where do you think 9/10 vendors get their products to relabel as their own, unless it is hand made it probably comes from a chinese/taiwan manufacturer. Sorry USA

• 3/8" Spring Hose Clamps (left over from Evo)
• Misc Mounting Hardware

-Used the 1/2" pinch clamp for the fitting on the intake tube as the fitting is for 5/16" hose, and this fitting allowed me to squeeze the 3/8" hose down nicely. It is a pain to get to, so I wanted a maintenance free clamp.
-Used the 5/8" pinch clamp for the 90* fitting coming off the PCV Valve. It is a pain to get to, so I wanted a maintenance free clamp.
-Routed the hoses under the cold air intake inlet and there is a good bit of room to loop them up back to the catch can fittings without any kinking of the hoses.
-Hose from the PCV valve coming off the block goes to the inlet of the catch can.
-Hose coming from the intake fitting goes to the outlet of the catch can.
-3/8" Drain Cock is for the bottom of the catch can for easy draining.
-1/8" NPT Tap is to drill & tap the back of the PCV valve.
**I removed the BMS catch can that I installed last month as it hasn't captured anything to date... absolutely nothing... when I popped my charge pipe off to get to the PCV valve, a good bit of oil came out again... I will monitor catch can collection and keep you guys updated.**


**UPDATE, AFTER 500 HARD MILES, I HAVEN'T CAPTURED ANYTHING YET, WILL POST AGAIN AT 1000 MILES**

Great job! I use pretty much the same catch can with a different name on my 93 Stroked Mustang. It does a pretty good job.
One thing to consider is the smaller the hose diameter equals more velocity and thus more collection and the opposite for a bigger diameter hose.

Its only 3/8" hose... every fitting is 3/8" except for the fitting on the intake which is 5/16"...

To be honest since working from home, I haven't really been driving the car a whole lot. Last time I checked it, with about 100-200 miles it had nothing in it... I will check it again soon.

Hows the catch can doing?

Still been working from home, probably only put around 300 miles on the car in the past 7 months... I will not check it until around the 1000 mile mark...

appreciate the time to list, post and share.

weird how people take off intake and there is oil but not many actually catching any oil??

Been a few years. Any update on this?

The catch can caught absolutely nothing. I have since removed the catch can and went back to a standard configuration.

So odd. I guess the only thing that makes sense to do is upgrade the valve cover to relieve pressure and implement port injection or Meth injection to mitigate carbon build up.
